IMPROVEMENT IN AUTOMATIC WATER CUT-OII'S.

To all whom it may concern.-

1 Be it known that I, D. F. SWEET, of Otsego, in the county of Allegan,and in the State of Michigan, have invented certain new and usefulImprovements in Automatic Water-Conductors; and do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon, making a part of this specification.

The nature of my invention consists in the construction of an automaticwater-conductor, which is to be attached to the water-spouts, so as toprevent the first washings from the roof from running into the cistern.

The accompanying drawing represents a section view of my invention.

LetterA represents the receiver into which the water flows as it comesfrom the eaves-trough.

From the bottom of this receiver there are two pipes running off, one,B, carrying off the waste or dirty water, and the other, C, conductingthe clean water to the cistern. The mouths of both of thesepipes areclosed, one at a time, by the double valve D, which has a strip ofleather attached to its lower sides, so as to make it water-tight.

To the valve, inside of the pipe 0, there is secured a weight, G, whichkeeps. it closed for a short time after it begins raining, while thepipe B is open, and receives the first water, containing the soot anddirt, from the roof.

In the bottom of the pipe B, there'is a hole or opening, which isregulated by the valve H, so that the water can leak into the cup K,placed underneath.

This cup is also attached to the valve by means of the rod or cord L,and serves as a counterpoise to the weight G.

"is the water flows through. the pipe B, it runs slowly into the cup,until it is full, when it overcomes the resistance of the weight, andcloses the pipe B, when all the water at once flows into the cistern.

In the bottom of the cup there is a small opening made for the water toleak through, anala piece of cloth, or some suitable material, placedover it, so as to prevent the dirt from closing it.

Through that part otthe valve which closes the pipe -B there is a smallapertnre made, so that the water can continue to leak into the cup insutficient quantity to keep the cup full during the whole time that itis raining. If it were not for this opening, the cup would soon beempty, and then the water would cease to flow into the cistern, as theweight G would cause the valve to close the pipe 0; but, as the cup iskept full until after the rain has stopped falling, only the very firstwater is lost.

After the rain is over, the cup soon becomes empty, when the pipe 0 isat once closed, and remains so until'the next rain. I

By means of the cut-off valve, the time for the closing of the pipe Bcan be readily regulated.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is-

The combination of the receirer A with its valveseats and valve 1),}theweight G within the pipe 0, I and the cup K, connected to one part ofsaid'valve,

under the cut-01f H and pipe B, the several parts constructed andoperating substantially as herein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand andseal, this 8th day of June,

D. F. SWEET. [L. s.] witnessesz.
